Description: 恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略，以重复控制器提高逆变电源输出电压的稳态精度，减小总谐波畸变率；以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240 DSP控制芯片的50 Hz三相PWM逆变器上得到验证。-Constant voltage constant frequency (CVCF) Inverter output voltage waveform quality is an important measure of its performance indicators. Paper using a repetitive control and the combination of double closed loop control voltage waveform control strategy to improve the repetitive controller output voltage inverter steady-state accuracy and reduce total harmonic distortion to achieve a faster dual-loop controller dynamic response speed. The program uses TMS320F240 DSP in a 50 Hz phase control chip PWM inverter has been to verify.

Description: This program has been written using Matlab/Simulink software. It can be used to find out the behavior of the induction motor behaviore when fed from a PWM inverter. The program is written so that the user can simulate any induction motor he wants by just loading the electrical and the machanical parameters in the workspace. The induction motor is modelled by the 7th order dq model which takes the iron loss component into account. The motor works in open loop but the closed loop can be easly performed by just adding the vector controller or any other controller and a PI speed controller.-This program has been written using Matlab/Simulink software.

Description: The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.-The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block.
